I had been wearing progressive lenses for about 10 years. I took to them like a duck to water. No problem.
Then I got a new Rx (probably my 4th by then). I put them on and said "something's wrong".
The tech said, no, it will just take you a little time to get used to them. OK.
I started driving home and was literally feeling sick with them, dizzy. Took them off and put my old ones back on.
Then I went back to the eye doc to ask them to check the numbers they wrote on my Rx.
Sure enough, they had made a mistake with the eye test (new doc or whatever they are).
They said that they should have called me back, but hadn't done it yet
I went back in, had a new eye test and they called
Sams Club (where I got the wrong Rx)
and asked them to make me a new pair, no charge.
Moral of the story, sometimes they make mistakes and it isn't you!
